摘要
传统的电子战接收机或雷达接收机无法识别同时到来的宽带雷达信号,只能依据测频参数移动频域接收窗口实现非实时宽带侦察或接收。提出一种新式的宽带数字接收机研制方案,利用多相滤波器组形式设计信道化接收机,从而降低硬件工作参数要求,实现真正的宽带侦察与接收。
The traditional EW or radar recetver can＇t distinguish broad-band radar signals arriving at the same time. It only can move receiving window on frequency field according to the code of frequency measure in order to realize non-real-time board-band reconnoitering or receiving. A new form of broad-band digital receiver is proved and simulated,which designs digital channelized receiver based on polyphase filter banks. This design can lower the demand of chips or circuit which can realize true broad-band reconnoitering and receiving.
